SPINNING MACHINE.

Application filed January 6, 1923. `Serial No. 611,045.

To all whom t may concern:

Be it known that I, WILLIAM SHAW, Sr., a citizen of the United; States', residing at Esmond, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvementsin Spin-- ning Machines, of whichthe followingis a speciiication. v

This invention relates -to spinning machines and more particularly to novel means for winding the roving on the bobbins in fly frames and the like, and the primary objects of the invention are first, to provide means for eliminating all strain on the cone belt, second, to provide means for shifting from equal speed of the driveV shaft and bobbin drive gear to excess speed and vice versa, and third,` to make the cone into a driven member instead of a drive member, to permit the carrying out of the various features of the invention. Y

It is a further object of the invention to provide means for revolving the bottom cone in the opposite direction tol that when` the frame is running, when it is'desired to wind the roving on the bobbin.

A still further object of this invention is to provide an improved differential mechanism for spinning machines, of the above character, which will be durable and eilicient in use, onev that will be simple'and easy to manufacture,rand one which can be incorporated in spinning fly frames Q at a minimum cost.

-With these and other' objects in viewA the invention consists in, the novel construction, arrangement and" formation of parts7 'as will be hereinafter more specifically described, claimed and illustrated in theaccompanying drawings, forming a part of this specificatiominV which drawings:

Figure v3 is a detail lsection taken on the 1 line 3 3 of Figure 1 looking" in thefdirection of the arrow.

Figui-c4 is a'` detail ,section taken on`v the f line 4*-4 ofFigure 1 looking in the direction of the arrow, and i Figure 5 is a detail section taken on the line 5 `5 of Figure 1.-

Referring Ito the drawings in detail, whereinsimilar reference characters designate vcorresponding parts throughout the several views the vnumeral 10 indicates the main drive-shaft, having a pinion 11 keyed to one end thereof, which is adapted to mesh with an idle pinion 12, having contact with the drive pinion 13. This drive pinion 13 is keyed or otherwise secured to the top cone shaft 14C, on which is mounted in any preferred way the usual top cone 15. The bottom cone 16 is of course similar to the topcone 16 and has the apex or tapered portion thereof disposed opposite to the tapered or apex portion of the top cone 15. The

bottom cone 16 is mounted upon a suitable Vshaft 17 carrying a relatively large spur gear wheel 18, which inturn meshes with a relatively small spur gear Wheel 19 "substantially the same diameter and areY pro- Vvided withthe same number of teeth. The

iii-neri end of the sleeve' 22 is provided with a cylindrical-shaped housing 24 which has 'formed on its innersurface an internal ring gear'25, which Vcan be considered in this instance as having forty-eight teeth. A cross 'piece' 26 is keyed to the main drive .shaft 10 and disposed within the cylindrical housing 24 andhas its opposite terminals supporting outwardly extending studs 27, on whichare rotatably mounted gears 28 and 29 and gears `30 and 31. The gears 28 and 29 can be considered as having sixteen teeth,

"while the gears 30 and 31 can beconsidered as having thirty teeth. The gears 28 and y297'/I mesh with the internal ring gear 25, while the gears 30 and 31 mesh with avgear 32, whichcan be considered as having eight- Aso een teeth and this gear can be keyed or otherwise secured to second sleeve 33 rotatably mounted upon the drive shaft 10.

VSplinedtor the second; differential sleeve 3 3 is av sliding differential sleeve 34:, which has secured to its inner end a large spur gear 35, which meshes with a relatively small pinion 3G, which is keyed to the inner endof the lower bottom cone driven shaft 20. The opposite end' of the sliding differential sleeve 34 from the-sun gear or. beveled gear 35 has formed thereon/clutch teeth 37 for engagement with the teeth 38.0f a nonesliding clutch section 3,9, which is se-. cured to the main drive shaft l0. rThe sliding differential sleeve 3d can be shifted by a suitable shifting yoke 40, which can be carried by a lever lll, which Vis roeliably lfriouiited upona Suitable pin .4.2,A that ie. to. secured to any preferred' part ofthe frame. it can be seen that when the sliding Asleeve 34 is shifted so. that the teeth 3T Vwill. mesh with the teeth38 of the non-sliding Vclutch section 39 that the gear 35 will be moved out of engagement with the pinion 3,6,i Vilhe lever l1, has pivotally connected theretoA at a point intermediate its ends a .link t3 which is Connected to the short arm of a bell, erank lever 44. This bell eranl; lever is rQCllbly iiiouuted at ite angle upon e, Suitable .piu i5 eeiiied by any pifeieii-ed,v part. of the freine.- A, beetle@ le iiveteflly ooiiueeted. to tbe olutei end of the long arm. of the leverl and has slidably connected thereto -rod t7 which is connected with a suitable collar i8 mounted upon the lower coneshaft l? and it can be seen that when the lever il isactuated to Slide tlie Sliding difereutiel Sleeve. it that the. bottoiu frame. een. be. Stopped eudytlie bottoni eoliel eau be raised Wliielil le ueeeeeapy to run over the ends for delfing. The slot iii the. bead 46 gives ample spate. to. permit the .bottom Cone to be lift'edby hanelwfllghut iueliiiis e dieeoiiueotiou, aedeeeiibed above, which is necessary at timeswhen the .end slackens, and the bottom cone mustv :be turnedbaekto give the slackl ends the proper tension.

ItWill readily seen, that when the gear 35 is held stationary, .the .speed of the .bobbin drivesgear 23 Will-be increasedy onereuolution forv every five .revolutionsthat the driving shaft 10` makes. l

The `operation is follows: The cross pieceQf being keyed to the drive shaft 1 0, eauses the gears 3,0, and fillgto, circle. gearf and assuming gear 32 asstanding-still, gear 23 will gain one fifth of a revolution. Sno

it tliue een be eeen that bobbiee etesireu their highest speed when the gear 32, is Stopped- Tliue ett-lie besiuuiusof. e. eetof revises, Wlieii tbe bobbipe. elfe driven.A et their bislieet Speed,l tlieeolie-belt is ou .the small end of the top cone and on the large differential uiliifoli iiiill-.elieetiizelfy bold die re end of the bottom cone, in a condition reveiisedifft'oni general npft'ofd'ate-- fly frames. When the cone belt is given a lateral motion at each change of the traverse, the

Vspeed of. .the .bottom` .eene inoieeeediivbioli takes. rev. ations .from geary oi s to tlie inereased .eed et the gearz lzY'liep tlie set of rovings are completed, the cone 1G is raised.- and a disconnection is caused, the gear 35, being pulledout of mesh with the gear 36 and a connection made between the sliding differential sleeve 34 and the non: sliding clutch section 39, which locks the Wholeinechanism asone .piece and thus the gear 2,3vi, e, the bobbin drive. gear and the gear 2l., which rdrive the spindles revolves the saine speed and no. Winding. takes place.

On fly framesofs the usual construction, at times, when the bottom cone is raised, if the same is not., heldE stationary by some means, it will revolve in the opposite direotion and malte considerable tronble by breaking and tangling the ends. This statement otloouree beers' out the feet, that e greet amount of resistance is exerted on the cone belt.
